Abstract (en)
An exhaust manifold integrally cast with a turbine housing (40) for a turbocharger has pipe portions (21,22) having a plurality of ports (11-14) each connected to each exhaust outlet of an engine for introducing an exhaust gas; flanges (11a-14a) each integrally extending from each exhaust gas-introducing port; a converged portion (30) of the pipe portions (21,22) for smoothly converging exhaust gas flow paths in the pipe portions; and a turbine housing (40) integrally connected to the converged portion for introducing an exhaust gas into a circular exhaust gas flow path therein. The turbine housing (40) is integrally connected to the converged portion (30) such that the exhaust gas flow path in the converged portion is in a tangent direction relative to the circular exhaust gas flow path in the turbine housing. A neck portion (32) in which an outer surface of the turbine housing is connected to an outer surface of the converged portion at a particular angle has a radius of curvature that is 0.13 or more in terms of a ratio to the distance in a tangent direction of the exhaust gas flow path from the center of the turbine housing to the converged portion. <IMAGE>
